I just purchased a 2011 Sierra 1500, quad cab, and as will all my vehicles i just cant leave it alone. i have been looking at lift kits for a while and cant decide which to go with. Im looking for something between a 4 and 6 inch lift and wondered if anyone has experience with any. I still want to be able to tow my jeep and figure 8 car from time to time. (yes i know a lifted vehicle isnt the greatest idea for towing) Any helpful input is greatly appreciated.
